LASTING AND FASTENING MACHINE.

SPECIFICATION forming part of Letters Patent No. 248,544, dated October 18, 1881.

Application filed September, 19, 1881.

To all whom it may concern Be it known that I, ERASTUS Woonwaan, of Somerville in the county of Middlesexand State of Massachusetts, have invented a certain new and useful Improvement in Lasting an'd Tacking Machines, of which the following is a full,clear, and exact descriptiomreference being had to the accompanying drawings, forming a part of this specification, in explaining IO its nature, in Which- Figure 1 is a front elevation of a machine embodying my invention. Fig. 2 is a plan of a portion of thejack-operative mechanism below the line 00 x of Fig. 1. Fig. 3 is a side elevation thereof. Fig. 4 is a side elevation, en-

larged, of a part ot'said mechanism, hereinafter referred to. Fig.5 is a plan view of the entire machine. Fig. 6 is an enlarged view of a part of thejack-operative mechanism. Fig.7 is a view, in elevation, of the jack and upper part of its operative mechanism turned a quarter to the right from the position shown in Fig. 1. Fig. 8 is a side elevation of the upper part of the machine. Figs. 9 and 10 are detail views.

This invention relates especially to mechanism for lasting the uppers of boots and shoes; but it may also be used for other purposessuch as the temporary tacking of an outsole to the insole after the lasting process, or the fast- 0 euings of stit't'enings, welts, or counters to the insole-and for a great variety of other usesin which it is desirable to drive fastenings rapidly and with precision.

It embraces, first,the combination or organ- 5 ization in one machine of devices for driving i'astenings having start and stop motions, and a jack for presenting the work to be operated uponlto the driving devices, so constructed and operated in relation to each other that theplaco ing in position of the work to receive thefastening will cause the fastening to be automatically driven or the machine to be automatically 'set in operation and automatically stopped; second, a jack of peculiar constructiomwhere- 5 by the inclination of the work to be operated upon is varied automatically, so that it always presents the proper inclination or position to the action of thel'astenin g-drivin g mechanism; third, a jack and operative appliances adapted to be lifted by a foot-treadle in presenting the (N0 model.)

' work to the fastening-driving mechanism, and

to fall rapidly to their original or lowest position by their own weight upon the release of the treadle; fourth, the combination and or-, ganization of a jack having an upward movement in relation to the fasteningdriving devices, and a yielding guide of sufficient length to extend below the last when at its lowest level, so that it may serve to direct the upward movementof thejack to the nozzle of the fasten-- 6o ing-driving device, as hereinafter explained; fit'th,the organization, in a lastinganachine, of devices for driving fastenings, heel and toelasting plates, oreither, and ajack adapted to trans fer the work from the fastening-driving device 6 5 to said heel and toe lasting devices, or either, whereby the side portions of the upper maybe lasted with the assistance of thefastening-driving device, and the work then moved without beingtaken from thejack to said lasting-plates.

In the drawings,A represents the standard or post of the machine. To the top of this standard is secured a. machine, B, for driving fastenings; and the machine which I prefer to use contains the invention described in Patent N o. 24= (i,437, granted me August 30, 1881, or, in other words, has the start and stop motions therein specified.

The jack 0 may be of any suitable construction for holding the last at its heel and toe, and it and the adjusting mechanism, hereinafter spoken of, are supported by the rod 0, which is hinged or pivoted at its lower end,c, to the arm or lever 0, so that the rod 0 can be moved in any horizontal direction in relation to the post A. This hinge-connection, to be more specific, consists of the socket 0 supporting the rod 0, and havingdownwardly-projecting lugs or ears 0, which straddle the plate or sleeve o to which they are fastened by the pivot 0 The plate 0 is adapted to swivel upon the pivot 0 projecting horizontally from the end of the lever 0 This lever is pivoted at its inner end, 0 to a suitable support and has projecting from its side an arm, 0 5 which connects the lever c with the treadlelever 0 This connection is shown in Fig. 2. The treadle-lever is pivoted at c.

Between the rod 0 and the jack 0 there are two devices for adjusting the position of the I00 jack. The first or upper device, D, consists in appliances for changing the inclination of the last while it is being revolved in presenting the work to the fastening-driving appliances, and the second, E, is a simple adjustment for varying the position of thejack in relation to the axis of the rod, and this last device comprises a plate, a, from the upper end of which projects upwardly the arm or plate a, and which has the curved slot near its lower end. This slotted plate is pivoted at e to the plate 0 which is fastened to the upper end of the rod 0 by a set-screw and socket, c

The plate e is locked in any desired position in relation to the plate 6 by means of the screwstud e", which is fastened to the plate a and projects through the slot 0 and the thumbscrew a The device D, for automatically changing the inclination of the jack or the level of the surface of the insole, consists of the arm or plate 0, above referred to, and the block (I, upon which t-hejack rests, as shown in Fig. 6, and which is pivoted to the plate 0 by the pivot d. This block (1 contains a shaft, (1 which is fastened at its upper end, (P, to the lower part, d of thejack, and revolves therewith, and it carries the bevel-gear wheel d, which meshes with the bevel-gear wheel (.1 This bevel-gear wheel (1 has a cylindrical extension or barrel, across the face of which is cut a long slot, (1 It has a bearing in the block (1. In the slot (77 is a block,d,arranged to be adjusted therein when desired, and from which projects the stud or pin (1", which extends through the slot (1 in the upper part of the plate 6. This pin or stud plays up and down from the axial center of the gear (1 ac cording as it is desired to throw or move the block d in relation to the plate or arm 0, and is in substance an adjustable crank-pin, by varying-the position of which in relation to the said center of the bevel-gear the extentof movement of said blockdiscontrolled and regulated.

The method of adjusting the stud or pin in the recess (1 and the manner of locking it in position by means of the thumb-screw al may be effected as shown in Figs.9 and 10; or the block 61 may be made in two parts and a projecting ledge on either side of the recess extended between them sufliciently to permit them to be clamped thereon by the stud or pin which passes from the inner plate, to which it is rigidly fastened through the outer block, the sleeve, or roll which surrounds the stud and the thumb-screw d.

In order that thejack may not turn too easily upon the block 61, I interpose the coiled spring f, surrounding the lower end of the shaft (1 between the nut f and the lower surface of the block d, which acts to draw the jack to the block with stress enough to create sufficient friction for the purpose between the two parts. A bracket or support, Gr, through which the post 0 passes, and which is fastened to the standard A, holds the jack and its supporting mechanism in an upright position.

' Ihave shown in the drawings plates for-lasting the heel only; but it will be obvious from the following description that toe-lasting plates can be used in lieu thereof, or that they can be arranged atthe right hand of the standard and beused in connection with theheel-lasting plate. These heel-lasting plates are shown in Figs. 1 and 5 as attached to the end of the arm G, projecting laterally from the standard; but, of course, they may be supported by an independent frame, if desired. They are lettered g, are pivoted at 9, have the arms 9 which extend backward, and have projecting upwardly the pins g which enter the curved slots in the lever which is pivoted at g. It is obvious that the movement of the lever closes or opens thejaws or plates 9 according to the direction of its movement. These lastingplates should have such alocation in relation to the fasteningdriving device that the jack 0 can be moved from the one to the other, or, in case toe-lasting plates are used additionally to them, and if for any reason the surf-a cc of the insole should become inclined from a horizontal position, or substantially a horizontal position, on account of this movement, the said plates may be operated on a corresponding level, instead of on a horizontal plane.

Of courseldonotcontinemyself to the methodot' operating thelasting-plates shown, neither do I confine myself to hinged lasting-plates described; but I may use, in lieu thereof, any of the well-known constructions, and I name, among others, those described in the various Copeland patents, so-called, the chief object of this portion of myinvention being to arrange the lasting-plates, either toe or heel, or both, in such position in connection with the device for driving fastenings that the work may be moved from the one to the other without being removed from its h olding-j ack. The upper, thus folded upon the surface of the heel or toe, or both, may be united to the insole in any desirable manner.

It will be observed that the machine for driving fastenings, instead of being provided with a foot or projection extending below the nozzle, through which the fastenings are driven, described in said Patent No. 246,437, has what I consider an equivalent device in substance, (for which I am about to make a separate appli' cation a movable nozzle-that is, the lower end of the nozzle is vertically movable and takes the place of the foot or projection of the said patent. In all other respects the intermediate connecting mechanism between the nozzle and the starting and stopping devices is substantially the same. It will therefore be seen from this description that the act of placing the work in proper position for receiving the fastening starts the fasteningdriving mech anism, drives thefastenin g, and stops the mechanism; and as the workis presented to the n0zzle of the fastening-driving machine by means of a foot-treadle, it will also be observed that the act of depressing the treadlc not only places the work in proper position to receive the fast- IIS Masha a ening, but also causes the fastening-drivin g m achine to be actuated. f

Of course it is obvious that the connection between the treadle and jack and the fastening-driving machine, whereby the fastening may be driven upon the proper positioning of the work in relation to the nozzle to receive the fastening, may be somewhat different in construction .from that above described and yet be the equivalent therefor. This method of operating the machine would be produced if the treadle had, for instance, an independent arm or rod connecting it directly with the device forstarting the machine, whereby, when the work is placed in proper position, the machine shall be by that act of positioning put in operation; or the connection may be between the jack itself or any portion of its supporting mechanism and the actuating mechanism of the fasteningdriving machine; or an independent treadle and rod connecting it with the actuating device and fastening-driving machine can be used, the said treadle being so placed as to be operated by the foot at the instant the work is properly placed in relation to the nozzle of the fastening-driving machineto receive the fastening; or a properlylocated device to be moved by hand for thus operating the fastening-driving machine might be employed.

In order that the work may be easilyguided or directed or steadied while it is being lifted to the nozzle of the fastening-driving device, I have arranged back of the nozzle the guide H. This guide is an improvement upon that described in the pending application of Jno. 0. Bond, and differs from it in two teaturesfirst-, in extending downwardly a sufficient distance to extend below the upper surface of the last when it is at its lowest position, in order that in lifting the last it may not be moved under its lower end, but may be moved against it at once by'a horizontal movement and may follow it from this lowest level to the nozzle; second, in having an adjustment whereby the extent of its movement may be varied or limited. This device consists in the stud or block it and the screw it. The spring 71, passes between the inner surface of the head of the screw and the outer surface of the stud, and of course the space between these two surfaces determines the extent of movement of the spring, and consequently the extent of movement of the guide. This guide, it is hardly necessary to say, is a yielding one, and in that respect is like the guide described in said Bond application.

In the process oflasting the uppers of boots and shoes with the mechanism herein de scribed, the upper is adjusted upon thelast in the usual manner, and the last is mounted on the jack. The operator then seizes with pinchers or with his thumb, and Jfinger a proper section of the upper margin, which he draws upon the surface of the insole while the last is in its lowest position. He then with his foot lifts, by means of the foot-treadle and connecting mechanism, the jack and last to the nozzle of thetastening-driving machine,and either while so doing or before, revolving the jack so that the part of the upper to be tacked shall be immediately below the nozzle. With his hands vhe moves the-jack horizontally toward the guide H either before he commences to lift it or while he is lifting it, and he steadies and guides the work in its upward direction to the nozzle from that point thereby. The instant that the work is in position to receive the fastening the fastening is driven, or, in other words, the very act of properly locating the work to receive the fastening causes the fastening to be driven.

Upon the driving of one fastening, if a wide section of the upper has been drawn over upon the insole, as before stated, thejack is lowered a little by means of its own gravity and the partial release by the foot of the treadle, and is again raised to receive the second fastening, and so on until the section drawn over is properly secured, the foot in every instance governing the lifting-and-falling movement of the jack. Upon the driving of the last fastening in the first section drawn over, the last and jack are dropped to their original position, another section of the edge of the upper is taken hold of and folded upon the surface of the insole, the jack revolved to bring that section into line with the nozzle and is again lifted to the nozzle, and the operation of driving the fastenings, as above described, is continued. This drawing over and folding of the edge upon the surface of the insole and fastening thereto may be continued until the entire upper is lasted, or it may be confined to the sides alone or to the sides and heel; and in this event the toe or heel, or both, may be lasted by independentmechanism. In such case, after the lasting by this process is completed, the part to be finished, either toe or heel, or both, is brought in line with the foldingdates by the movement of thejack, and is presented by the hand and by foot to said folding-plates, and the plates closed upon the surface of the insole, folding the edge of the upper thereon automatically. The edge thus folded is then fastened by means of hand-driven fastenings or by power-driven fastenings, driven singly or in a group. i

It will be noticed that the jack-adjusting devices are so contrived that the last is always in the best position when under the nozzle to receive the fastenings, or,in other words, the last should be always so inclined in relation to the nozzle that the fastening shall be driven upon the line which, if extended, would pass through the center, or very nearly the center, of thelast,and the construction ofjack-operating devices herein described automatically locates the last in this desirable position. t It is obvious that if the machine be run somewhat slowly the stop-motion, which is described as automatic, may be independently actuated.

For the purpose of working the fasteningdriving machine in the way intended itis only essential that there should be a tack-driving mechanism which, when the shoe is not presented to it for the reception of the tack, shall be at rest. This tack driving mechanism, so normally at rest, must be thrown into revolution by the release of a catch, and the machine must be provided with a stop-motion which preferably is actuated automatically, as described.

The advantages of this invention consist, principally, in the speed and ease with which the lasting can be done.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In an organized machine for lasting and tackingthe uppers 0t boots and shoes, the combination of ajack and last adapted to be operated by a foot-treadle to present the work to the nozzle of an automatic fastening-driving device, and the automatic fastening-driving device whereby the lastand jack are presented by the foot to the nozzle of the fastening'driving device, a tack or nail driven, and thejack and last automatically adapted to resume their original position upon the release ot' the treadle, substantially as described.
